9aab3f2be0 Add memory utilization analytics to mallctl 
The analytics tool is put under experimental.utilization namespace in
mallctl.  Input is one pointer or an array of pointers and the output
is a list of memory utilization statistics.

978a7a21ae Use iallocztm instead of ialloc in prof_log functions. 
Explicitly use iallocztm for internal allocations.  ialloc could trigger arena
creation, which may cause lock order reversal (narenas_mtx and log_mtx).

6fe11633b0 Fix the binshard unit test. 
The test attempts to trigger usage of multiple sharded bins, which percpu_arena
makes it less reliable.

788a657cee Allow low values of oversize_threshold to disable the feature. 
We should allow a way to easily disable the feature (e.g. not reserving the
arena id at all).

b804d0f019 Fallback to 32-bit when 8-bit atomics are missing for TSD. 
When it happens, this might cause a slowdown on the fast path operations.
However such case is very rare.

06f0850427 Detect if 8-bit atomics are available. 
In some rare cases (older compiler, e.g. gcc 4.2 w/ MIPS), 8-bit atomics might
be unavailable.  Detect such cases so that we can workaround.

atomics).

cbdb1807ce Stringify tls_callback linker directive 
Proposed fix for #1444 - ensure that `tls_callback` in the `#pragma comment(linker)`directive gets the same prefix added as it does i the C declaration.

18450d0abe Guard libgcc unwind init with opt_prof.

some bootstrapping issues.

dca7060d5e Avoid redefining tsd_t. 
This fixes a build failure when integrating with FreeBSD's libc.  This
regression was introduced by d1e11d48d4
(Move tsd link and in_hook after tcache.).

9015deb126 Add build_doc by default. 
However, skip building the docs (and output warnings) if XML support is missing.
This allows `make install` to succeed w/o `make dist`.

e13400c919 Sanity check szind on tcache flush. 
This adds some overhead to the tcache flush path (which is one of the
popular paths).  Guard it behind a config option.

e3db480f6f Rename huge_threshold to oversize_threshold. 
The keyword huge tend to remind people of huge pages which is not relevent to
the feature.

350809dc5d Set huge_threshold to 8M by default. 
This feature uses an dedicated arena to handle huge requests, which
significantly improves VM fragmentation.  In production workload we tested it
often reduces VM size by >30%.

d3145014a0 Explicitly use arena 0 in alignment and OOM tests. 
This helps us avoid issues with size based routing (i.e. the huge_threshold
feature).

bbe8e6a909 Avoid creating bg thds for huge arena lone. 
For low arena count settings, the huge threshold feature may trigger an unwanted
bg thd creation.  Given that the huge arena does eager purging by default,
bypass bg thd creation when initializing the huge arena.

f459454afe Avoid potential issues on extent zero-out. 
When custom extent_hooks or transparent huge pages are in use, the purging
semantics may change, which means we may not get zeroed pages on repopulating.
Fixing the issue by manually memset for such cases.

fc13a7f1fa Remove --branch=${CIRRUS_BASE_BRANCH} in git clone command. 
The --branch parameter is unnecessary, and may avoid problems when

4e920d2c9d Add --{enable,disable}-{static,shared} to configure script 
My distro offers a custom toolchain where it's not possible to make
static libs, so it's insufficient to just delete the libs I don't want.
I actually need to avoid building them in the first place.

7241bf5b74 Only read arena index from extent on the tcache flush path. 
Add exten_arena_ind_get() to avoid loading the actual arena ptr in case we just
need to check arena matching.
